PR202-Quinacridone Magenta

PW7-Zinc Sulphide White

Pigment Name

PR202-Quinacridone Magenta

Pigment Type

organic, dichloroquinacridone

Properties

PR202 has a bluish red color, but is more yellow than Quinacridone Red (PR122), which is the modern favorite for Magenta in CMYK (four color) process printing.

Permanence

Although it is not the most famous magenta in the quinacridone family of pigments, PR202 belongs to a related class chemically, and is thus relatively stable and permanent for a bluish red pigment. It is one of the pigments often used in inks and toners for process printing.

PR202 has been widely used as an automotive paint. Other applications include packaging, printing inks, and textiles.

Pigment Name

PW7-Zinc Sulphide White

Pigment Type

inorganic

Chemical Name

zinc sulfide

Chemical Formula

ZnS

Properties

Zinc Sulphide White is a semi-transparent yellowish white pigment. Zinc sulfide and zinc oxide (PW4) are often combined to create a more natural white color. Transparency increases as particle size decreases. When slight impurities are added, zinc sulphide has phospherescent and electroluminescent properties. It is often used to manufacture fluorescent or glow-in-the-dark paints.

Permanence

Zinc Sulphide White has excellent permanence and lightfastness.

History

Zinc sulfide, when combined with slight impurites, has phospherescent properties. It is often used for "invisible ink" that glows with exposure to ultraviolet light. Zinc sulfide is used in the manufacture of fluorescent paints.
